Congratulations on the purchase of your National Luna portable fridge / freezer.

The National Luna range of portable fridges and freezers are high-performance, high efficiency 

refrigerators ideal for harsh conditions and applications that are limited to battery power such as off-

road vehicles, caravans and solar installations.
The versatility of each of the National Luna models allows the use of a wide range of AC supply voltage 

(85V DC - 265V AC) as well as 12-volt or 24-volt battery power (9.6V AC - 31.5V DC).
The use of a custom-designed digital thermostat and smart control circuitry ensures temperature 

stability and low power consumption.
All refrigerator models are built using high quality materials, unique assembly techniques and strict 

testing procedures to ensure the highest level of quality and performance.

Introduction

Precautions

When the refrigerator is used in an automotive application, ensure that it is secured to prevent 

accidental movement. The carry handles can be used with straps or tie-downs if necessary.

• 

A base mounting plate is optional and recommended for most applications.

• 

Allow a 50mm gap around the refrigerator compressor area for ventilation. 

• 

Do not block or cover the ventilation holes.

• 

Ensure the correct type of cable and connectors are used for installation.

• 

Ensure that any power leads connected to the refrigerator will not be pulled or damaged by  

 

  any movement of the fridge - especially where slides or drawers are used.

• 

Do not use a power lead that is damaged.

• 

Do not connect the refrigerator to a power source that does not comply with the input   

 

  power specifications. (Displayed on the fridge’s rear panel)
• 

When storing the fridge, ensure that the lid is propped open to allow for aeration. Disconnect the  

  appliance from an electrical source. (Note: When the fridge is switched off, the interior light will still  

  function if the unit is connected to a power source).
